adding power seats 92

I own a 92 maxima and am currently trying to install used power seats from another 92 maxima replacing the original manual front seats. Does anyone know what I need to do to get power to the new seats and what connectors I will have to puchase if any. The seats I have bought have two more connectors attached to the underside of each seat for which my car is not set up for. Any info would be greatly appreciated.
